Abstract

A key blank, key and master keying system for a twisting tumbler sidebar lock of the type where the sidebar is blocked or unblocked by a selectively positioned longitudinally extending slider, has a key blank with a slider contacting surface on a rib on the blank below the bitting area at one of a plurality of selected predetermined locations. A key with skew cut bittings can be cut on the blank and the blank can be configured with the slider contacting surface at different predetermined locations. The slider contact area on the rib of the key blank can be divided into two horizontal portions at different predetermined locations and the slider itself can have contact surfaces also positioned at different predetermined locations so that a number of different master keying variations are possible.

Claims

1. The key blank used to make a key from it with cutouts and serrated protrusions for a lock with a crossbar made in the form of a locking plate, which is connected with switching pins moving along the screw path and blocking or releasing the crossbar with a key head made on the head an abutment adjacent to the head of the key blade with a working face with grooves and serrated protrusions and located on the blade, horizontally divided into at least two sections by a protruding edge, which, when spanner is inserted into the keyhole, the lock acts on the slider, wherein the slider acts on the rib is located on one of the sides of the key blade, and its front end is at least one selected location at a certain distance in the longitudinal direction of the key head.

2. The key blank according to claim 1, in which the sections of the rib acting on the slider are located in the horizontal plane at different distances from the plane of the key blade.

3. A cylinder lock together with keys made of at least two blanks according to claim 2, with at least two sections of the rib acting on the lock slider, and a slider that locks or releases the lock bolt, which is connected to the switching pins moving along the helical path and in the keyhole of which two faces are arranged in a specific manner on the slider, the position of which allows you to insert at least two keys made of different blanks into the keyhole.

4. A key for a lock with shifting pins moving along a helical path, which are affected by serrated protrusions made on the working face of the key, with a crossbar made in the form of a locking plate and a slider that locks or releases the crossbar, while the key has a head made on the head emphasis with which the key inserted into the keyhole abuts against the end of the lock; a blade with a working edge located on the upper edge with a plurality of serrated protrusions located along it, and a protruding rib located at least in two sections horizontally divided into at least two sections, which, when the key is inserted into the keyhole, acts on the lock slider and the sections of which rest against the slider moving it and freeing the lock bolt.

5. The key according to claim 4, in which the rib has at least two sections that act on two different sections of the slider.

6. The key according to claim 4, in which the rib sections acting on the slider are displaced in the direction of the longitudinal axis of the key relative to each other in the horizontal plane.

7. The system of locks with a master key, which consists of locks with a crossbar made in the form of a locking plate, which is connected with switching pins moving along a helical path and a slider blocking the crossbar, and keys according to claim 5, and in which the keys have sections that act on the corresponding sections of the slider, and are made in such a way that one key inserted into the keyhole acts on the slider and changes its position in the lock, and the other key inserted into the keyhole does not affect the slider action.

8. The system of locks with a master key, which consists of locks with a crossbar made in the form of a locking plate, which is connected with switching pins moving along a screw path and a slider blocking the crossbar, and a key with two horizontal sections acting on the slider located in different lengths the key in certain places, and in which the sliders of the locks have faces located in different specific places, the combination of which with different parts of the key acting on them allows you to create a system with a master key Chom from a large number of locks.

9. A lock system with a master key, which consists of locks with a crossbar made in the form of a locking plate, which is connected with switching pins moving along a screw path and a slider blocking the crossbar, and a key with a section acting on the slider, the end of which can be in different the length of the key in certain places, and in which the sliders of the locks have faces located in different specific places, the combination of which with different parts of the key acting on them allows you to create a system with a master key from a large number of castles.
